          """
          Add a new edge between two existing nodes in a network. The names of the
          nodes must be specified and much match the value in the 'name' column for
          each node.
  
          :param isDirected (string, optional): Whether the edge should be directed
              or not. Even though all edges in Cytoscape have a source and target, by
              default they are treated as undirected. Setting this to 'true' will
              flag some algorithms to treat them as directed, although many current
              implementations will ignore this flag.
          :param name (string, optional): Set the 'name' and 'shared name' columns
              for this edge to the provided value. ,
          :param network (string, optional): Specifies a network by name, or by SUID
              if the prefix SUID: is used. The keyword CURRENT, or a blank value can
              also be used to specify the current network.
          :param sourceName (string): Enter the name of an existing node in the
              network to be the source of the edge. Note that this is the name as
              defined in the 'name' column of the network.
          :param targetName (string): Enter the name of an existing node in the
              network to be the target of the edge. Note that this is the name as
              defined in the 'name' column of the network.
